   This happens because the feed dogs pull the fabric along more on one side than the other.

   You could baste the seam to keep the fabric in place but it is just as easy to pin it.

   The solution is to, first, match the seamlines and pin them at the beginning, at the end and at any notches. Put the beginning of the seam under the presser foot & lower the needle into the fabric. Hold the fabric tightly with your fingers about 1/4 or 1/3 of way along the seam and start sewing down to your fingers, stop and move your hand along another section and continue this way until you reach the end of the seam. Do not pull the fabric along, let the feed dogs do their job.

   Holding the fabric tightly will keep one side from being pulled along a bit faster than the other. After some practise, you can dispense with the pins.

   This is really good technique. Still, in spite of doing this I often have this problem anyway. To cope with it, I stop sewing about 2/3 of the way down the seam. If the two edges are not going to match up, I stop sewing and take the seam out of the sewing machine, and restart sewing the seam from the opposite end. This flips the top and bottom of the two pieces you are sewing together, and allows the natural tendency of the feed dogs to push the top piece faster than the bottom piece to solve the problem of the uneven edges.
